Displaying a barcode on a display of an infusion pump

ABSTRACT

An infusion pump system includes an infusion channel, and a display associated with the infusion channel. The display is for rendering a scannable barcode.

BACKGROUND

Use of an infusion pump in conjunction with a Bar Code Medical Administration (BCMA) system requires that the infusion pump present a barcode. Typically, this barcode is manually attached or adhered to an infusion channel of an infusion pump. This barcode is scanned to associate a medication order with the infusion channel. The use of this approach has many issues. For example, correlation of the BCMA systems identification information with that of other means (e.g., wireless networking), cleaning of the infusion pump, barcode label loss and subsequent replacement.

Moreover, the symbology, format and content of the barcode used to identify the pump channel is specific to the BCMA system used. The manufacturer of the infusion pump's barcode is not used, and there is no universal standard for the barcodes compatible with BCMA systems.

DESCRIPTION OF EMBODIMENTS

Reference will now be made in detail to embodiments of the present technology, examples of which are illustrated in the accompanying drawings. While the technology will be described in conjunction with various embodiment(s), it will be understood that they are not intended to limit the present technology to these embodiments. On the contrary, the present technology is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the various embodiments as defined by the appended claims.

Furthermore, in the following description of embodiments, numerous specific details are set forth in order to provide a thorough understanding of the present technology. However, the present technology may be practiced without these specific details. In other instances, well known methods, procedures, components, and circuits have not been described in detail as not to unnecessarily obscure aspects of the present embodiments.

FIG. 1 depicts an embodiment of infusion pump system 100. Infusion pump system includes infusion pump 110. Infusion pump 110 includes at least one infusion channel 120 for providing an order of medication to a patient.

Infusion pump 110 also includes at least one display 130. Display 130 is for rendering a scannable barcode 150 generated by barcode generator 140.

Additionally, display 130 displays user-readable information. For example, in addition to displaying barcode 150, display 130 also displays information such as, a name of the pump, patient name, drug dosage, etc that are able to be read by a user.

In one embodiment, display 130 is a transmissive display (e.g., backlit LCD display) with sufficient contrast and resolution such that an image scanner is able to scan barcode 150. In another embodiment, display 130 is a reflective display (e.g., electronic paper).

Barcode 150 is any optical machine-readable representation of data. For example, a 2-D barcode. In general, barcode 150 uniquely identifies infusion channel 120. For example, barcode 150 is utilized to associate infusion channel 120 to an infusion order.

In one embodiment, barcode 150 includes a Uniform Resource Locator (URL). When scanned by an appropriate configured mobile device, a browser on the mobile device is able to view the given web page associated with the URL and display its contents. Moreover, this functionality allows a user access to context-sensitive instruction material (e.g., videos, diagrams, etc.) or to information on a particular device alarm or malfunction.

Barcode 150 can be static information or dynamically changing information, which will be described in detail below.

Barcode generator 140 receives input 145 to facilitate in generating barcode 150. Input 145 can be, but is not limited to, configuration data, unique device data and system state. Barcode generator 140 assures that each barcode is compatible with the barcoding application (e.g., a BCMA system) in use.

In one embodiment, barcode generator 140 dynamically generates barcodes for display on display 130. For example, display 130 dynamically displays a first dynamic barcode when infusion pump is at a first state and dynamically displays a second dynamic barcode when infusion pump is at a second state. In another example, display 130 initially displays a barcode indicating a channel identifier, but changes to displaying a barcode indicating infusion status in response to a clinician pressing a button/key on infusion pump 110.

Unique device data is information particular to infusion pump 110 and/or infusion channel 120. For example, model number, serial number or MAC address, etc.

System state information allows barcode generator 140 to change the generated barcode that is rendered on the display to dynamically change in real-time according to the current state of infusion pump system 100.

Configuration data is information associated with the current configuration of infusion pump 110. It specifies what is to be displayed on display 130 for each applicable system state.

In one embodiment, configuration data indicates how to construct the data to be encoded into barcode 150. For example, data to be encoded may include a fixed field plus a field containing the device serial number. In another example, the barcode data could be a unique identifier generated by a particular rule from the device serial number and/or model number.

In another embodiment, configuration data includes a specification of the format, symbology and encoding used to create the barcode image from the barcode data. For example, configuration data can be configuration data from a plurality of different BCMA systems. Moreover, the configuration data can be stored on memory on infusion pump 110 or from an external configuration system.

In a further embodiment, a user specifies a configuration by selecting support for a particular BCMA system or by making lower level, more granular choices. The configuration may be applied through device settings or via a clinical dataset. Moreover, configurations may be institution wide or vary by care area.

Input 145 can include dynamic data (e.g., configuration data and/or system state) such as, but not limited to, medication order information, infusion status, drug information, dosage information, volume infused, volume remaining, patient ID, clinician ID, etc.

Accordingly, infusion pump system 100 can utilize the dynamic data to aid in charting. For example, to facilitate in populating an automated flow sheet or Electronic Medication Administration Record (eMAR). The dynamic information can be used to confirm handling of an automated order that is transmitted back to a medication administration system.

Barcode scanner 180 is for scanning barcode 150 rendered on display 130. Barcode scanner 180 can be any scanner capable of scanning barcode 150 displayed on display 130.

In one embodiment, display 130 is integrated into infusion pump 110. For example, display 130 is integrated in the form factor of infusion pump 110. In particular, display 130 is integrated into infusion channel 120.

In another embodiment, display 130 is a separate component that is attached to a legacy infusion pump or infusion channel. Accordingly, display 130 includes barcode generator 140 or is able to wirelessly receive barcode 150 from barcode generator located in another medical system.

Display 130 is disposed at a location that the correspondence between the infusion channel and the barcode is obvious to a clinician.
